- Study how the dose of CS-1008 effects where the CS-1008 distributes in the body (biodistribution), how long it circulates in blood (pharmacokinetics) and how much attaches to tumour (tumour uptake). These issues are studied after the initial infusion of 111In-CS-1008 (CS-1008 tagged with a small amount of radioactive Indium - also called Indium-111 or 111In), and also during and after a cycle of weekly infusions of CS-1008 antibody.
